Why Is My Check Engine Light On? A Lake Worth Mechanic Explains

If the check engine light just came on in your car, you're probably wondering whether it's something serious or something you can put off. Here in Lake Worth, Boynton Beach, and West Palm Beach, our team at Affordable Auto Repair & Tire runs check engine light diagnostics every single day, and the honest answer is: it depends on what's triggering it.

Common reasons your check engine light turns on

A loose or damaged gas cap, a failing oxygen sensor, a worn-out catalytic converter, spark plug or ignition coil issues, or a problem with the mass airflow sensor are some of the most frequent causes we see. Some are quick, inexpensive fixes. Others, if ignored, can lead to bigger repair bills down the road.

Solid light vs. flashing light

A steady check engine light usually means it's safe to keep driving for a short while, but you should get it looked at soon. A flashing check engine light is more urgent, it often signals a misfire that could damage your catalytic converter, and you should reduce your speed and get to a shop as soon as possible.

What our diagnostic service includes

We connect your vehicle to a professional OBD2 scanner to read the exact trouble codes your car is reporting, then explain in plain English what's going on before any work begins. No guessing, no surprise charges.
